Be it knownthatLWINFrELD O. GUNCKEL,

a citizenl Vof '-the- United States, residing at Terre Haute, in thecounty of Vigo and State of Indiana, have invented certain new anduseful Improvements in Roller-Bearings and I do hereby declare thefollowing to be. afull,- clear, and exact description of the invention,

' such as will enable othersskilled Ain the art ing annular extension c,of chill-hardened- .30

to Whichit appertains to make and use the same. A

This invention relates to roller-bearings for the axles or' car-Wheels;and it consists in the novel construction and combination of thepartshereinafter fully described and claimed; In the drawings, Figure 1 is afront view of a car-Wheel provided with a roller-bearing according tothis invention, the outer coverof l the bearing.beingremoved. Fig. 2 isa section through the same, taken on the line Qca: in Fig. l. A is theaxle of a car, and B is a car-wheel journaled on the end of the axle.The wheel B is provided with a central .cavity b, which `n1ay befilled-With lubricatingmaterial, if de- I sired. The cavity bisformed-between't'wo internal flanges C in the Wheel-hub B', ,and each`flange C has onits outer .side a projectmetal. C fare chambers outsidethe said flanges. rI hese chambers are formed .in the I hub of the wheelconcentric with .the axle,

and their'peripheries are chill-hardened and form roller-races. Thecar-wheel is made of cast-iron or steel, and-the smooth land hardsurfaces of the said annular extensions and roller-races are formed byembedding plates of metal in thefmold in which the wheel is cast tochill the metal of the Wheel at the de sired places. 1

E `is the cover for the outer end of the wheel and axle. This cover isprovided with a chill-hardened projecting flange e arranged opposite onef the annular extensions c and.

parallel with it when the cover is secured in position.

Fis an annular cover for the inner end of the \\hecll111b. This coverhas a chill-hardened' projecting flange: fopposite and parallel'to theother annular extension c. The-groove fl is for the collar on theWheel-axle 'Lto run in when the axle is provided with a collar.

Gare bolts which pass through holes in the co ers and in the wheel-huband .secure the covers in position. :1'

Hare large rollers interposed between the ers Hand the roller-races. Therollers H and h are cast in chills to make them smooth and hard'allover. ,The rollers ru'n between 4the projecting annular extensions andflanges c ind) e and c and f at each end of 4the Wheel' I is a' grooveinthe-axle A.- One s et of rollers H runs in this groove and preventsthe axle from slipping endwi'se out of the hub of the wheel. .Thechamber inclosing the groove -I is show smaller in diameter than theother chamber, utilsV is obvious that both chambers may be made of the.same diameter if the 'di anreter of the rollers Hwhich run in thegroove axle-and the roller-races, and h are small rollers interposedbetween'the adjacent roll- I be ncreasedinproportion t'o the depth ofthel said groove. The same device may be used tosupport arevolvingshaft,the Wheel-y hub Vbeing held 'stationary and then being equivalentto a bearing-block. Whatlclaimisf- .Thecombinatiom lwithv an axleprovided with a circumferential groove cfa vhub provided ,with a chamberat each end of it having. outwardly-projecting chill-hardened annularextensions and chill-hardened `roller races; covers secured one at eachend of the hub and provided with inwardly-projecting chill-hardenedianges; and chill-hardened rollers H and h running in the said'chambers,the large rollers H engaging with the said groove, substantially as setforth.,

In testimony whereof I afx my in presence of two Witnesses.V
